Did you tried the hidden menu ? maybe there is something about the turbo.

You have to push the start button and the trip reset button simultaneously for a couple seconds(not pushing brake pedal)then ad the sum of the five last digits in the vin (like 5 if if you have 11111) and enter the sum in the right sub-menu.

I didnt try it.

Does anybody know how this works.

The only things that come up are:

Main Menu

01 ID
02 System Test
03 Test End
04 Unlock

I can cycle through with the trip button, but nothing else changes anything.

1. Press and hold trip and start until "main menu" appeared
2. Press trip 4 times until '04 unlock' highlighted
3. Press and hold while on '04 unlock' until next menu shows
4. Next menu asks for a code
5. Press trip as many times as x (code will count up)
6 When you get to the right number do another press and hold on trip and multiple more menus appeared

Might have the words/description a little off, perhaps I should video it...

Now this works!!! Thanks

I did manage to add the "Service Menu" for CIC settings to the "Setting Menu" on the iDrive for Navigation, Telephone and Gracenote.

One thing that I really miss having on the X3 35i is a turbo boost gauge. Every turbo-engine car Iíve owned has either had a factory-installed gauge or Iíve installed an Autometer electronic boost/vacuum gauge myself. Getting the required wiring harness for the Autometer gauge installed is not a trivial job, since it means running a cable through the firewall.

Anyway, I thought a way around having to do that on the X3 might be to see if the boost pressure value was available through the OBD-II port. The pressure reading is certainly something the engine control CPU monitors, and many vehicles do allow it to be read out via the OBD-II port. Usually the reading is accessed by checking the MAP (manifold absolute pressure) value. Unfortunately, the X3ís port does not respond to a query for a return of the MAP value. It may not be there at all, or BMW may supply it only under a special (secret) query request.

Anyway, as long as I was connected to the OBD-II system, I decided to see what WAS available on the X3.

The X3 uses the CAN 11-bit protocol.

Here is a list of the digital values that can be read in real time on a X3 35i using standard CAN queries:
